Pennsylvania teachers heading out of state to find jobs. Hunting for a position as a first-grade teacher in Pennsylvania became a full-time job for Williams Township native Sarah Widmer.

By Definition. A single board foot of lumber measures 1 inch thick, 12 inches wide and 12 inches long. The formula for calculating board feet is first to multiply thickness by width by length -- in inches. Then divide the total by 144 for the total board footage of a given board.
Board Foot: Rough sawn lumber is usually sold by the board foot (bd. ft.). A board foot is equal to a piece of wood 12 inches long x 12 inches wide and 1 inch thick, or 144 cubic inches. To figure the board foot measurement of a piece of wood, multiply the length x width x thickness in inches, then divide by 144.
